Patent EP-0667644-A1 (EP)
Inventor: TAMAKI TUTOMU TOSHIBA ISOGO DA
IPC: G11C16/02
Filed: 1995-02-10
Abstract: On a p-type semiconductor substrate (1), n-type source and drain regions (4), a gate insulating film, and a gate electrode (3) are formed. The gate electrode is formed on the gate insulating film and across the p-type region between the source and drain regions. A channel region (10) is on the p-type region under the gate electrode. Isolation regions are on the both sides of the channel region. A p-type impurity diffusion region (9) is formed at least on one of the isolation regions by ion implantation self-aligned to the gate electrode and thermal diffusion. The effective channel width (Well) can be reduced to a predetermined value resulting in the channel conductive reduction. On the other hand, on a p-type semiconductor substrate, a plurality of n-type source and drain regions, a gate insulating film and a plurality of gate electrodes are formed. The source and drain regions are arranged in parallel to each other. The gate electrodes are formed on the gate insulating film in parallel to each other and across the source and drain regions. Channel regions are on the p-type regions between the source and drain regions under the gate electrode. A p-type impurity diffusion region is formed at least on one side of the channel region by ion implantation self-aligned to gate electrode and thermal diffusion. The effective channel width of the memory cell is narrowed by forming the impurity diffusion region extended into the channel region, resulting in lower channel conductance. The first memory cells have the channel not including the impurity diffusion region. The second memory cells have the channel including impurity diffusion region. The channel width of the second memory cells is narrower than that of the first memory cells. Further any one of the threshold voltages of the first and second memory cells can be determined higher than that of the other thereof by ion implantation.

Abstract: A method of purifying NOx-containing exhaust gases characterized by using ammonium acetate as a reducing agent to a zeolite-based catalyst. NOx in NOx-containing exhaust gases can be removed extremely effectively even at a low concentration thereof by using Fe-treated mordenite as a zeolite-based catalyst according to said method, and since it uses ammonium acetate as a reducing agent, an excellent effect free from ammonia slipping can be obtained. 
     Particularly NOx in NOx-containing exhaust gases can be removed effectively at and around a discharge temperature of an exhaust gas from a gas engine in the presence of ammonium acetate as a reducing agent by constituting Fe-containing mordenite as a monolithic material. Hence, it makes it possible to obtain an excellent effect of simplifying the whole denitration system without needing temperature control of an exhaust gas and/or a catalyst bed. In addition, the NOx-purifying ability of the catalyst does not decrease over a long period of time.

Abstract: In a tyre tread band for medium/heavy duty motor-vehicles a tread band is provided with circumferential grooves (2a, 2b, 2c) confining three pairs of respectively centre (5c), intermediate (5b) and shoulder ribs (5a). Respective blocks (7b, 7a) are defined along the centre and intermediate ribs and they are confined by transverse cuts (8b, 8a). The centre cuts (8b) impart a cusp-shaped end conformation (9) and a hollow-shaped end conformation (10) to the respective blocks (7b), and the shapes of said end portions mutually match. The intermediate cuts (8a) run in the linear extension of the centre cuts (8b) to give the respective blocks a rhomboidal configuration. The tyre can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the centre blocks at the ground-contacting area.

Abstract: Bei bereits bekannten Brennstoffeinspritzventilen werden verschleißeanspruchte Bauteile, wie z.B. Anker und Kern, mit verschleißfesten Schichten beispielsweise aus Chrom, Molybdän oder Nickel versehen. Erfolgt die Beschichtung der Bauteile des Einspritzventils galvanisch, so ergibt sich eine gewünschte keilige Schichtdickenverteilung, wodurch nur ein kleiner Anschlagbereich geschaffen ist. Diese Schichtdickenverteilung ist allerdings physikalisch vorgegeben und kaum beeinflußbar. Das neue Ventil besitzt wenigstens ein Bauteil, z.B. den Anker (27), der vor dem Aufbringen einer verschleißfesten Schicht eine gestufte Oberfläche besitzt, die entsprechend einem magnetischen und hydraulischen Optimum jeweils variabel herstellbar ist. Der durch die Stufe gebildete ringförmige Anschlagabschnitt (69) besitzt eine definierte Anschlagflächenbreite bzw. Kontaktbreite (b), die über die gesamte Lebensdauer konstant bleibt, da ein Anschlagflächenverschleiß bei Dauerbetrieb nicht zu einer Vergrößerung der Kontaktbreite führt. Das Ventil eignet sich besonders für den Einsatz in Brennstoffeinspritzanlagen von gemischverdichtenden fremdgezündeten Brennkraftmaschinen.

Abstract: A rotary compressor, wherein a roller (6) adapted to fit over an eccentric portion (51) of a driving shaft (5) is relatively rotatably installed in a cylinder chamber (21) of a cylinder (2), a blade (61) provided in such a manner as to integrally protrude from the roller (6) is oscillatably supported on a support (62) which is rotatably disposed in the cylinder (2). Then, an oil groove (64) opening to the axial end of the roller (6) is formed in the internal circumferential surface of the roller (6) and on a counter-loading side between the blade (61) protruding position and a position displaced 180 degrees from that position in the rotating direction of the driving shaft (5), and oil is positively supplied from this oil groove (64) to the sliding surface. Due to the configuration described as above, although it is an oscillating type rotary compressor in which the roller (6) performs relative rotations, the rotary compressor described above provides good lubricating conditions on the external circumferential surface of the eccentric portion (51) of the driving shaft (5) and the internal circumferential surface of the roller (6), whereby seizing wear are prevented, thereby improving reliability.
